Jack - The weather is beautiful in October. It's usually in the mid 70s typically in October. Definitely a favorite time of the year for the locals and guests that can make it here during that time.
Typically the weather is in the 70's and 80's. If you wish to see what is projected for October 2016 you can go to the Accuweather website and enter Panama City Beach and it will show you the projected temperatures. Personally I enjoy going at this time as the crowds are less and the weather is SO pleasant!
